Re: [RE-wrenches] Retrofit BMS

I have used Nuvation BMS with Nissan Leaf batteries in a off grid hone. They have been running for 2 years and the cells are staying within 0.02 volts. There are a lot of parameters to set but their tech help is great. They can drive 4 relays based on almost anything you can think of and they also

Re: [RE-wrenches] Buck/boost converter

Hi Dave, I have used these: https://www.analyticsystems.com/products/voltage-converters/ They aren't cheap, but you can parallel them up to that capacity. Solid for about 3 years so far. On Sat, May 4, 2019 at 10:15 AM Dave Angelini Offgrid Solar < offgridso...@sti.net> wrote: > I am looking

[RE-wrenches] Generator for DC Coupled System

Folks, Has anyone had the chance to work with the Polar Power DC generators such as https://www.polarpower.com/wp-content/uploads/8220K-972_0115.pdf ? Anyone aware of good alternatives? Thanks, Mark Frye ___ List sponsored by Redwood Alliance

[RE-wrenches] Buck/boost converter

I am looking for a recommendation for a buck boost converter with an input of arround 42 -62 vdc and an output of 57vdc. I would like something around 50 amps or larger. Is there one? Thx! Dave Angelini Offgrid Solar "we go where powerlines don't" http://members.sti.net/offgridsolar/ [1]

[RE-wrenches] Retrofit BMS

Wrenches - I have an opportunity to take possession of some lightly used 2 kWh Lishen LFP battery packs for next to nothing. What's the catch? No BMS. Anyone have any experience retrofitting a BMS on Li+ batteries? This looks interesting , and this EV BMS

Re: [RE-wrenches] Lithium batteries

Thanks Jason. Great videos! Any thoughts on why AES is so much more than some others that seem pretty solid as well? Howie On Fri, May 3, 2019 at 5:30 PM Jason Andrade < ja...@westcoastsustainables.com> wrote: > > Howie, > I’ve used a few different brands and am currently using the Discover
